IMPROVEMENT IN CAR-AXLES.

Specification forming part of Letters Patent No. 222,108, dated November 25, 1879; application filed March 20, 1879.

To all whom 'it may concern:

Be it known that I, SAMUEL D. WEBSTER, of Canon City, in the county of Fremont and State ot'Oolorado, have invented a new and useful Imprm'ementin Duplex Axles, of which the following is a specification.

Figure 1 is aplan view of my improved axle, the upper parts of the bearin gs being detached. Fig. 2 is a detail cross-section of the same, taken through the line a" 00, Fig. 1. Fig. 3 is a detail longitudinal section of a part of the same, taken through the line z y, Fig. 4. Fig. 4: is a top view of oneof the bearings, the oilcup cap being removed.

Similar letters of reference indicate corresponding parts.

The invention consists in combining the bearings, cap-plates, oil-cups, stop-pins, and spring-catches, as hereinafter described.

A and B are the parts of the axle, to which the wheels 0 are applied in the usual-way. The axle A is forked or divided near the inner side of its wheel to receive the other part, B, of the axle, so that the axes of the two parts may be in the same line.

To the part A of the axle, at the inner and outer ends of its forks, are attached bearings D, to receive the journals of the other part, B, which journals have shoulders or collars at each end, to prevent them from having any longitudinal movement in their said bearings. Each bearin g D is made in two parts, bolted to each other and to the arms of the partA of the axle, and in each of the said parts is formed an oil-cup, d, to receive lubricating material. The oil-cups cl are covered with cap-plates E, which are slipped into grooves in projections formed upon the said bearings. The cap-plates E are kept from being pushed too far by stop-pins 6, attached to the bearings D, and are held in place by springs 6 also attached to the said bearings D, and the shoulders of which rest against the rear edges of the said plates E.

The arms of the forked part A of the axle may be made rectangular or half-round, or concavo-convex, or semi-tubular, or of any other desired shape. l

Having thus described my in ventiou,I claim as new and desire to secure it by Letters Patent The combination of the cap-plates E, the stop-pins e, and the spring-catches c with the parts D of the bearings, provided with oil-cups d, substantially as herein shown and described.
